"The Mystery of Lyle and Louise"

Isolated from sewage, human intestines, and urinary tract infections. Spreading colonies are seen on agar growth medium. 

Both of these strains of Serratia marcescens are colorless mutants when plated alone, but when grown together, they produce a red pigment.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.

Beta hemolysis on blood. Causes wound infections and septicemia. 

This yellow, shiny organism is known to cause wound infections and more famously, toxic shock syndrome.

Grows on dead tissues. Novobiocin resistant (S. epidermidis and S. aureus novobiocin sensitive). 

No Lancefield group shown, alpha hemolysis. Bile solubility test positive, optochin sensitive. Causes pneumonia. 

Isolated from human saliva, sputum, and intestine. No Lancefield group shown, alpha hemolysis.

This organism can be isolated from many human urinary tract infections, as well as polluted water and sewage. It is commonly identified by its distinctive grape-like smell (trimethylamine) or because it can turn the agar light green due to production of a blue pigment (pyocyanin).

Lancefield group A, beta hemolysis. Sensitive to bacitracin. Causes strep throat, rheumatic fever, and scarlet fever.

Isolated from human urinary tract and wound infections, this organism is identifiable by its characteristic putrefactive odor. 

Demonstrates isogamous reproduction where gametes are similar in appearance and behavior. Make lectures and labs on protist reproduction clearer with our specially selected cultures that illustrate various reproductive phenomona.

Paramecium aurelia is the smallest species of Paramecium we offer. Paramecium aurelia is characterized by cilia, which it uses for locomotion and feeing. Contains a macronucleus and two micronuclei. Grows in Dilute Alfalfa Medium (Hay Medium).

Erpobdella obscura

Cockroaches are widely used in labs for physiological, behavioral, structural, and developmental studies.
